The ultimate chip upgrade for the B6 A4 1.8T engine is available from NGP and APR! After months of long nights and many hours of dyno work, APR is pleased to offer you chip tuning that is second to none. APR have worked hand in hand with many customers to deliver a chip that works. Expect huge increases in low-end torque, improved throttle response and a smoother, more powerful top end.

Stage I ECU Upgrade

Stage I software gives you 215 horsepower and 245 lb-ft. of torque. This software is the ultimate upgrade for the B6 A4 and gives it just the extra edge these cars lack from the factory, without pushing the limits. With factory like smoothness and drivability, the new power will fill the void in an otherwise excellent car.

Stage I+ ECU Upgrade

Stage I+ software, along with larger fuel injectors, provides even more horsepower and torque, raising the output to 235 and 275, respectively. While not an extreme upgrade, the Stage I+ gives the A4 a bit more performance without sacrificing drivability or smoothness. For optimal results, the APR cat-back exhaust system is highly recommended with the use of the Stage I+ system.

APR chips are available in an octane specific version for the octane of gasoline that you typically run in your car. The power that the chip makes also depends on which ECU is in your vehicle. The A4 1.8T ECU can be upgraded with either the use of a soldered in EMCS module, or DirectPort Programming. For more information on DirectPort Programming and EMCS hard chip options, please email us at info@ngpracing.com.
